No one has banned political subjects on HN. There was a brief experiment to see what the site would be like without them—it was scheduled to last a week, instead it lasted 2 days, and we've never dreamt of trying anything like it since.

Right, I was speculating about what it would be like and my thoughts on that, IF it were so. But perhaps it came off as me commenting "a change on HN".
I'm glad to hear you've never dreamt of trying anything like it since. :)
